Subject [jira] Commented: (DERBY-2280) DatabaseMetaData.getTypeInfo() UNSIGNED_ATTRIBUTE and AUTO_INCREMENT column returns incorrect information for BLOB & CLOB data type
Date Fri, 20 Apr 2007 16:15:15 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12490396
] 

Kathey Marsden commented on DERBY-2280:
---------------------------------------

Yes, the double negative is confusing:
UNSIGNED_ATTRIBUTE= false means it IS a signed type.
UNSIGNED_ATTRIBUTE=true  means it IS NOT a signed type.

So my thinking is that only numeric types should have UNSIGNED_ATTRIBUTE=false
The rest should have UNSIGNED_ATTRIBUTE=true
